5. If the condition in step 4 is met, place max. 2 pieces of wood with a
total weight of 1-1.5 kg and a length of 2025 cm over the embers in
a single layer, with a distance of approximately 1 cm.
6. Open the air supply to maximum, and close the door. The
fresh wood will be lit within 1-3 minutes.
If it does not light, open the door slightly to allow in enough air to ignite
the wood.
Close the door again once the wood has caught.
Important!
It is important that the fresh quantity of wood starts to burn quickly. To
ensure the fuel lights quickly, open the combustion air to max. or leave
the door ajar to allow in the amount of air needed to light the wood.
If, however, the wood only smoulders, there will be a strong build-up
of smoke, which at worst can cause an explosive ignition of the flue
gases with the risk of material damage and personal injury.
7. Reduce the amount of combustion air to the desired position, and the
optimal combustion will continue. Make sure that there is always
enough air (oxygen) to maintain clear, lasting flames when, and after,
reducing the amount of combustion air.
Make sure that there is always enough air (oxygen) to maintain clear,
lasting flames when, and after, reducing the amount of combustion air.
The stoking interval is between 45-75 minutes.
8. Once the fire has been reduced to a thick layer of embers, a new portion
of wood can be added by repeating steps 5 & 7.
The stove door must be opened gently the first 2 - 3 centimetres, then
you should wait until the pressure has equalised before opening the
door all the way. This technique will prevent smoke from getting out,
particularly when there is a poor draught.
The stove door should never be opened when the stove is being fired vigorously.
Once the wood has burned out, it becomes glowing charcoal. If a good layer of embers has already
formed on top of a sufficient layer of ash, the stove can keep warm for a very long time, not least due
to the favourable qualities of the cast iron.
Precaution with the use of Morso 7300/7400 in
Smoke Control Areas
The 7300/7400 has been recommended as suitable for use in smoke control areas when
burning wood logs with less than 20% moisture.
• Refuelling on to a low fire bed
If there is insufficient burning material in the firebed to light a new fuel charge, excessive
smoke emission can occur. Refuelling must be carried out onto a sufficient quantity of
glowing embers and ash that the new fuel charge will ignite in a reasonable period. If there
are too few embers in the fire bed, add suitable kindling to prevent excessive smoke.
• Fuel overloading
The maximum amount of fuel specified in this manual should not be exceeded, overloading
can cause excess smoke.
• Operation with door left open
Operation with the door open can cause excess smoke. The appliance must not be operated
with the appliance door left open except as directed in the instructions.
• Dampers left open
Operation with the air controls or appliance dampers open can cause excess smoke. The
appliance must not be operated with air controls, appliance dampers or door left open
except as directed in the instructions.

We would strongly recommend that you do not leave your stove alit at night. It harms the
environment, and constitutes very poor use of the wood, as the gases in the wood do not ignite
at the low temperature, but settle as soot (unburned gases) in the chimney and stove. Extreme
conditions, such as poor draught in the chimney, large quantities of wood or wet wood, may,
in the worst-case scenario, cause an explosive ignition.
When firing in the summer period, when there is minimal need for heat, the combustion will
be poor. The stove provides too much heat, so the combustion should be reduced. But always
remember to make sure that there are lasting flames until the wood becomes charcoal. If you
want a weaker fire, stoke up using less wood.
